I am going back to my youth as an electronic engineer to design some stuff.
I have joined hoping for help.
This will be the start of a few minor project around building a cockpit for online flying. Basically, Arduino boards loaded with code and game libraries to detect game events. Coding is a new area for me. I’m pre PCs back then
Anyway, my current problem is more descrete.
With Vcc at 5V and Gnd at 0v, why does my LM393N Op Amp output 0.7v when I/P 1(-) is connected to Gnd and I/P 1(+) is 2.5V by connecting to the middle of 2 x 5kOhm in series across Vcc and Gnd???
I was hoping to get 5V O/P to drive a MOSFET Board for a 12v power control over a magnetic field coil…
